Be it known that IQFREDERIOK Konriio, a citizen of the Republic ofSwitzerland, residing at Pittsburgh,in the county of Al legheny andState of Pennsylvania, have i invented certain newfand useful ln'provements 1n CrusherApparatus .TEOILCOH1O- tive Stoker's, of which thefollowing is a My invention relates to coal crushing apg paratus forlocomotivef-stokers, and is in the nature of an improvement inthe devicedescribed and shown in LettersPatent ofthe UnitedfitatesNo.fi1,258,l-20, grantec l to me lilarchr'th, 1918. u It has for oneotits p'riQ mar-y objects to improve the construction and increase the,ciiiciency andutility of devices ofthisicharacterfl Another object i ofthe inventionis to provide aconstrucw tion of crusher ,wherein thesingle'tree is jpivotally rnounted and may he quickly and easily"removed for replacement or repair upon the detachinent of but a singlencininvention normally userves tomaintain the single-tree in its p1v0tedp0s1t10n,

l My invention also contemplates certain novel details of construction,combination and arrangement of parts ofltheiinproved device; wherebycertain important advantages are attained, as will hemore fullydescribed l1ereinafter, and pointed out in the claimed i v Thesatogetherwith such other objects as are f incidentj to my invention, I attain hyjmeansof a construction illustrated in pr e 1 111111 the accompanyingdraw i t-s, wh e t it I Figureflt represents nal section through thefront portion Iofa locomotivetender such as is used with aua toniaticstoker mechanism totloconiotives;

and showing my invention as applied there to just below] the fueldischarge passage and above the hopper; p

t Figure 2 is a central vertical sectional view ofthe crusher shown inFigured, but

emiwh em central longitudimavbe briefly descrihed as follows. The

reference character A denotes a tuel re tenderBl, the base of which isprovided with a discharge outlet 5.- Disposed belowthis outlet is acrusher device G emhodyingwa casing 6 and a crusher 13 which is adaptedtobereciproc'ated in the casingtransversely of the outlet 5 by Ineansofthe links? and driving rod 8 usually carried on the loconioceptacle inthe front end of the locomotive tive. The reference numeral9 designatesa forward passage in thecrusher casingigfi into Which the fuel frornthereceptacle A falls by gravity, froinjwhich it passes through a dischargeopening 10 basally formed inthe casin then through the hopper 11, and

fuel is eventually discharged; in the well known manner, from the chute12 at the front end thereof into thestokermechanism vcustomarilycarriedby the locomotive.

In carrying; out my inventioml provid Itrom'thence into a transferjchute12 where the fuel is worked forward by the reciprocation cf the pivotedvanesl Thecrushed the side walls 14: ofthe crusher casing 6 v with anupper marginal flange 15 substantiallycodncident with andimmediatelyvbelow the marginal boundary of the outlet 5, l

endflalso with hearing boxes 14 affording hearingsfor the shafts 17which carry'the rollers 18upon which the crusher 13 recip rocates underthe influence ofthe links'i', During, its reciprocation, I the crusheris maintainedin its "proper avenue of travel bvmeans of'the rollerflanges 3.8 andthe marginal; flange 15 above'it.

The crusherfistransversely formed with i a central opening or slot19intermediate its toPwall 20 jand its base anthem this slotispivotally'mounted'a single-tree22 whose end-portions 22* extend inopposed directions through elongated slots 23 provided in the side Walls14 of the casing, the base 21 having an opening 24 leading downwardlyand outwardly from the slotted opening 19, The pivotal axis of thesingle tree 22 is embodied in the form of an agitator pin 25 i'vlioseshank 26 passes thrini'gh 7 are terminally connected:

One important advantage of my invention resides in the ease with whichthe singletreemay he removed from the crusherfor the purpose ofreplacement or repair, since all'that is' required in this connection isto uncouple the a itato'r andv siiigle-t'ree pin 25 and the'lifiks%endthen swing the single tree in a rearward' directien toward the Wall27 of the tender (Figure and Withdraw it ("jut of the left hand slots'19 and 23;

Theshslots, it ill be observed, are elongated sufficiently to permit ofthis swing withdrawingmovement: i

In order to control and regulate the crusher discharge opening 1-0 inrespect to lts discharging capacity, a coal cut-off slide plate'memher28 is provided to marginally rest up-nthe spaced supports 29 whicharelseehred to the lower facespf the Walls 1'4 aild honstitnte inwardlydirected extensions thereof. VVhile' the upper face of this-slidecut-olfis substantially coincident with; the lower face of the 'crusherbase 21-, tl'ie'reds" no 'c'ont ah't hetvv'een them, as the crusherrides'free-ly' on the antifriction rollers18. Above these'latter areprovided protecting bosses 30 for the roller hearii'igs.

shovv'n in the drawing,- the slide off is in itseiitrelneirear positionwith ref erence to the opening 10-, vvhose area or size of outlet it isdesigned to regulate as oc casion may require, and toetf ect thisregulation the -slide is adapted for movement transversely of this saidopening toward or away from the front Wall 31 of the crusher casingsThemeans provided in this connest-in contemplate a pair of coupling rodsWhose rear end portions are terminally connected with the arms ofarross-piece 34 Which is=holted t-o the underfa'ce of the front portionof the cutoff slide 28. and

'also' i'iicludes the rack 35; pinion 3t}- and handivheelfi'imanipulationof which, as will' he apparent, causes the regulatingmovement of the slide through the interposition of thehell-crank "lever38 whose ends are pivetally connected to the ends of the rack'and therods- It Will he noted that I thecross-piece' ioffset at 34% so as toposition its arms 33 in advance of the rollers and bearings so as toclear the latter rea ers ,to materially eti'ect its elliciency andutility.

It will he understood that the edge of: this opening 2 1 clears theslide when the crusher moves to its extreme retracted position from theintermediate position in the outlet 5 which-itis shown as occupying inthe drawings. The device has easy movement, is simple and eliicient,readily applied, and, as already indicated, the single-tree may he veryquickly removed and replaced.

What I claim is:

1. In a combination with a fuel. receptacle having a fuel outlet in itsWall of a fuel crushing device therefor comprising :1 casing disposedabout said outlet and provided with slotted side Wall portions and adischarge outlet, a reciprm-atin c crusher having its body portionformed with a slot Jllllnunirating with the slots of said portions, aregulating member controlling said discharge outlet said crusherslidahly sup ported in said casing independently of said regulating;member, and a single-tree incinher reinovably positioned in said slotsand having a pivot pin detachahly connecting it with the hot y portionof said crusher. said pivot pin positioned in said fuel outlet.

2. In combination with a fuel receptacle having a fuel outlet in itsWall, of a fuel crushing device therefor comprising :1 casino-disposedabout said outlet and provided with slotted side Wall portions and a discharge opening, anti-friction means carried by said portions, a rut-offslide for said opening, a crusher slidahly supported on said meansindependently of said slide and having its body portion formed with aslot erittending laterally to said slotted side por tions and openingdownwardly past said slide, actnatine means said crusher including sin'einovahly positioned in cnding ont- \vardly beyond said side portions,and an. agitator pin in said fuel outlet pivotallv connect-ing said menier to the hody portion of the crusher. subs antially as and for thepnrpose set forth.

A fuel crushing apparatus to ho applied to the outlet of a fuelreceptacle comprising in combination. a casing provided With a fuelinlet and a fuel outlet, a slide mounted in said casing, removableactuating means for the slide, and a fuel agitating pin on the slideremovahly mounted therein meeeee and adapted to act as the holding meanselotted side walls and an inlet and an outlet, a shcle mounted 111 Saulcasmg provided with an opening adaptedtoalign with the slotted sideWalls of the casing, a single tree in the slide With its: endsprojecting through the slots in the side Walls of the casing a fuelagitating pin mounted on the slide and acting also as a positioning andholding means for the smgle tree, the smgle tree being; removable upondetachment of the pin, and means adapted to be connected to the singletree whereby theslide is actuated.
